The PROTECT Study in Hong Kong

This study is an exciting opportunity to take part in a major worldwide research project that aims to understand how healthy brains age and why people develop dementia. PROTECT Hong Kong is run by the University of Exeter, UK in partnership with the Chinese University of Hong Kong.

“Understanding how the brain ages is a critical step towards preventing dementia in the future. PROTECT offers a unique and exciting way of gathering information about thousands of adults to support this innovative research. It will drive forward research into dementia prevention and healthy ageing in the UK and across the globe.”

Professor Clive Ballard, Dean of the
University of Exeter Medical School.

The time it takes to contribute to dementia research

Age icon


How old you must be to participate in the study

Who can participate?

You can join the study if you:

Are aged 50 years or older
Reside in Hong Kong
Do not have a diagnosis of dementia

What is involved?

Once a year, you will be asked to complete a set of questionnaires about yourself, your lifestyle and your health. Each takes an hour or less to complete. You will also be asked to take a series of online tests, to measure changes in brain function.

Examples of Questionnaires, Cognitive Function Tests and Brain Training Games:

Memory and Reasoning

Please rate yourself on how well you remember things about family and friends, e.g. occupations, birthdays, addresses.

Everyday activities

Please rate yourself on how well you manage your ordinary housework.


What is your current employment status?


How often do you drink caffeinated drinks (tea, coffee, energy drinks)?

Everyday Emotions

Have you noticed your behaviour being less spontaneous and active, for example, less likely to initiate or maintain conversation?

Medical History

Do you regularly experience pain that interferes with your day-to-day life?

Fertility and Menopause

How many children have you had?

Mental Health

People differ a lot in how much they worry about things. Did you ever have a time when you worried a lot more than most would in your situation?

Cognitive Function Tasks

Assess core aspects of brain function relevant to everyday activities including attention, memory, reasoning and processing

Brain Training Games

Set of games designed to keep your brain active


Cognitive Tasks
Repeat annually over 10 years

Brain training games can be played regularly throughout the year

The people behind the project

“PROTECT will drive forward research into dementia prevention and healthy ageing in the UK and across the globe.”


Professor Linda Lam

Professor at the Department of Psychiatry and Assistant Dean of the Faculty of Medicine of the Chinese University of Hong Kong

“Many people are puzzled about whether dementia is an inevitable part of ageing. PROTECT provides a cutting-edge platform that will help us learn much more about this, so that we can help formulate meaningful action plans to support people in staying sharp in older age.”


Dr Anne Corbett

Senior Lecturer, University of Exeter Medical School

“The internet presents a powerful opportunity for large scale global research that would not have previously been possible. PROTECT will rapidly progress research towards a better understanding of healthy aging and how dementia might be prevented in the future.”
